  • Patent number: 8304087
    Abstract: Process for treating wood consisting in injecting in cavities of the wood a solution of at least one fungicide and/or bactericide and/or insecticide and at least one monomer that can progressively form a polymer matrix in the cavities of the wood and then a gel in the cavities of the wood. The treated woods thus obtained exhibit an improved lifetime.
    Type: Grant

  • Patent number: 8298582
    Abstract: A polysaccharide-based solid material including, in its mass, at least one active agent having bactericidal, fungal, insecticidal and/or flame-retardant properties, and at least one complexing agent and/or at least one polymeric matrix having a complexing agent. The active agent includes at least one compound selected from the group including boron, silica, aluminum, phosphorus, iodine, derivatives thereof, aluminosilicate derivatives, and mixtures thereof. The solid material is characterized by an improved stability and by reduced environmental impact, and makes it possible to prepare materials based on wood particles and woods having a particular resistance against environmental attacks such as moisture.

  • Patent number: 6728982
    Abstract: A pediatric stretcher includes a base unit, attached to which are a number of lift assemblies. A frame is supported by the lift assemblies. Attached to the frame is a patient support deck. A railing is coupled to the frame by a plurality of coupling members and is configured to surround the patient support deck. The railing includes four individual rails, including a front rail, a rear rail, a left rail and a right rail. At least one of the four rails is configured to be raised and lowered with respect to the patient support deck and the plurality of coupling members. At least one of the four rails includes a gate that can pivot about a pivot axis. The gate is configured to be released and locked along the pivot axis.

  • Patent number: 4911995
    Abstract: Process of manufacturing thin electrodes, supported on a sheet substrate, the electrodes being made from an element selected form lithium, lithium alloy, or doped lithium, whose melting point does not differ from the melting point of lithium by +50.degree. C. and whose thickness is constant, from a roller of the sheet and a source of the element. According to the invention, there is provided a bath of the element in molten state, the sheet is continuously unrolled, a constant quantity of the molten element is continuously applied on one of the two faces of the sheet, so as to produce a film on the sheet, whose thickness is constant and between abouth 0.1 and about 40.mu. and whose surface is homogeneous and uniform. The process is carried out in such a manner that the molten element is prevented from solidifying while in contact with the sheet, and the solidification of the element on the sheet takes place after formation of the film on the sheet.

  • Patent number: 4824746
    Abstract: Process of manufacturing thin electrodes, supported on an electronically conductive sheet, the electrodes being made from an element selected from lithium, lithium alloy, or doped lithium, whose melting point does not differ from the melting point of lithium by .+-.50.degree. C. and whose thickness is constant, from a roller of the sheet and a source of the element. According to the invention, there is provided a bath of the element in molten state, the sheet is continuously unrolled, a constant quantity of the molten element is continuously applied on one of the two faces of the sheet, so as to produce a film on the sheet, whose thickness is constant and between about 0.1 and about 40.mu. and whose surface is homogeneous and uniform.

  • Patent number: 4794060
    Abstract: The disclosure describes an anode made of a thin metallic foil in discharged condition which is converted into a dense metallic alloy of an alkali metal during the first charge. The disclosure also describes an electrochemical rechargeable battery in discharged condition. The latter comprises an anode made of a thin metallic foil, such as aluminum, magnesium or tin, an electrolyte, for example a polymeric electrolyte, as well as a cathode based on an oxide, a sulfide or an halide, prepared in discharged condition and constituting a source of alkali metal preferably lithium. The cathode should be capable of freeing the alkali metal under a charge so that the latter is introduced into the metallic foil to form an alloy of the alkali metal and of at least a portion of the metal consitituting the metallic sheet. To obtain the charged batery, it is merely sufficient to apply a charge during a certain period of time while the anode is being transformed into an alloy.
